Abstract
Description
- This invention relates to a laundry washing machine comprising a gasket for a door having a central opening provided with a glass or the like, the gasket comprising two mainly U-shaped parts interconnected to one another, a first part surrounding the edge of the door that borders on the opening and a second part surrounding the edge of the glass and having a tab extending mainly perpendicular to a leg of the second U-shaped part for abutting the door glass and that the area between the leg and the tab supports a flange extending towards an outer drum of the laundry washing machine when the door is in a closing position.
- A gasket of the type mentioned above is previously known, see JP-04114693A and is used for front loaded laundry washing machines in order to seal the abutting area between the door and the outer drum of the laundry washing machine which drum during the washing procedure contains the washing liquid. A disadvantage of the gaskets previously known is that it is hard to close the door because a high gasket pressure is needed in order to achieve the necessary sealing effect and moreover the gasket has a tendency to become deformed when being acted on such that there becomes an opening between the glass and the tab of the gasket which means that there is a risk for leakage. A further disadvantage of the known arrangement is that there is a risk that dirt particles stick between the gasket and the outer drum when the door is closed which also means that leakage of cleaning liquid might occur.
- The purpose of this invention is to achieve a gasket for which the drawbacks mentioned above are eliminated and which has a less gasketpressure which means that the door is easier to close at the same time as the sealing function of the door is safeguarded. This is achieved by means of a device having the characteristics mentioned in the claims.
- An embodiment of the invention will now be described with reference to the accompanying drawing which in a section shows a part of a laundry washing machine having a door and a gasket according to the invention the door being shown in a position immediately before being closed.
- The
door 10 shown in the figure comprises an outer door part 11 preferably from sheet metal or aluminium having aninner flange 12 surrounding a central opening. The opening is covered by aglass 13 or some other kind of transparent material. The glass has aflange 14 that is arranged in parallell with theflange 12 of the outer door part the two flanges being surrounded by agasket 15 comprising two U-shaped interconnected parts 15a and 15b such that the gasket forms a mainly Z-shaped structure forming a sealing between the door part 11 and theglass 13. - The gasket that is manufactured from rubber or plastic, for instance EPDM, comprises a
tab 16 of one leg of the U-shaped part 15b thetab 16 abutting the glass of the door and extending mainly perpendicular to lastmentioned leg. The thickness of thetab 16 decreases towards the outer end of the tab. - The area between the leg of the U-shaped part 15b and the
tab 16 supports aflange 17 extending mainly 45° to the length direction L of the leg and whose imagined extension line when the door is closed meets a gasket abuttingsurface 19 of theouter drum 18 of the laundry washing machine at an acute angle α. Theflange 17 is at its outer part provided with sideways extendinglip 20, as seen in the length direction of the flange, the lip preferably having a thickness that is less or similar to the thickness of theflange 17. - The gasket works in the following way. When the door of the laundry washing machine is closed i.e. when it is moved in the direction denoted A in the figure the
lip 20 will get in touch with thedrum 18. Continued pressing forces on the door means that thelip 20 withhout greater resistance will be folded towards theflange 17 and seal against the drum at the same time as a moment is created on theflange 17 this moment pressing thetab 16 against the glass. By this arrangemant thetab 16 will always abut theglass 13 such that leakage can not occur between the glass and the tab. The arrangement also means that the sealing surface becomes self cleaning and hence less sensible that dirt particles stick to the surface and causes leakage since the gasket is rubbed against the drum each time the door is opened and closed.
Claims (6)
- Laundry washing machine comprising a gasket for a door having a central opening provided with a glass (13) or the like, the gasket (15) comprising two mainly U-shaped parts (15a,15b) interconnected to one another, a first part (15a) surrounding the edge ofthe door that borders on the opening and a second part (15b) surrounding the edge of the glass (13) and having a tab (16) extending mainly perpendicular to a leg of the second U-shaped part (15b) for abutting the door glass (13) and that the area between the leg and the tab supports a flange (17) extending towards an outer drum (18) of the laundry washing machine when the door is in a closing position, characterized in that the flange at its outer end is provided with a sideways extending lip (20), as seen in the length direction of the flange (17), which when the door is closed will seal against the drum (18).
- Washing machine according to claim 1, characterized in that the lip, when not being loaded, extends mainly 90° with respect to the length direction of the flange (17).
- Washing machine to claim 1 or 2, characterized in that the flange (17) extends mainly 45 ° with respect to said leg.
- Washing machine according to any of the preceding claims, characterized in that the thickness of the lip (20) is less than or equel to the thickness of the flange (17).
- Washing machine according to any of the preceding claims, characterized in that the flange (17) is arranged such that its imagined extension line, as seen towards the drum (18), when the door is closed meets an abutting surface (19) of the drum (18) for the lip (20) at an acute angle (α).
